RFC -> XI -> File

Hello,

I have a scenario where I must create a flat file from data in the SAP. I created a report that prepares the data and the calls RFC on destination 'XI' with the data.

This works and the file gets created but I am getting errors on the XI log. I guess it's because the RFC is expecting some kind of response.

Is there any way around this WITHOUT BPM? What will happen if I create an ASYNC message inteface for the RFC? will this help?

Thanks,

Yoni
